Smith, F., 1877
While the ant will nest in dead branches of trees of several genera, it favours eucalypts, and is known to tend Coccoidea (Ward 2001). Within the SWBP, T. punctulata is widespread and reasonably common, and can typically be seen foraging around the trunk of Wandoos. The unusually long, thin outline of this species makes it readily recognizable in the field. (Heterick 2009)

Ward (2001) - In common with other members of the T. laeviceps-complex, the worker caste of T. punctulata has an enclosed, pit-shaped mesopropodeal impression. T. punctulata workers can be distinguished from those of related species by the following features: (1) most punctures on head relatively small (typically about 0.010 mm in diameter), separated by several diameters, and contrasting with the coarser, denser punctures on the pronotum; (2) in profile dorsal face of propodeum more or less flattened or occasionally elevated posteriorly, but not depressed posteriorly; (3) posterior half of petiolar sternite strongly protruding ventrally; and ( 4) petiole relatively broad (PWI 0.50-0.70). In addition, the eyes are of moderate size (REL 0.30--0.39); appressed pubescence is rather dense on the body, especially on the postpetiole and gaster; and the petiolar node, while variable in shape, always has the posterior face descending gently rather than steeply from the rounded summit. Queens and males can be recognised by the features listed in the keys. Although there are apparently no surviving types of T. punctulata, the original description and the type locality leave little doubt about the application of this name.
Workers of T. punctulata show rather extensive and complex patterns of morphological variation. Body size varies considerably, even within populations. At some localities in north Queensland and Northern Territory it is possible to distinguish nest series containing either large (HW- 1.10 mm) or small (HW- 0.90 mm) workers, each occupying different Eucalyptus trees. The larger workers tend to have disproportionately smaller eyes, more elongate heads, and more robust petiolar nodes, but these differences appear to be due to allometric effects.
Head shape also varies geographically. In northern Queensland some T. punctulata workers have the propodeum conspicuously elevated, yielding atypically high PDI values (PDI > 1.1 0). The shape of the petiolar node varies continuously from rather long and slender to short and robust, with the most robust petioles (those with the highest PLI values) occurring in workers from northwestern Australia. Body pilosity ranges from sparse to common, as reflected in the range of CSC and MSC values, without showing any marked geographical tendencies. Standing hairs are always uncommon on the upper half of the head and on the mesonotum. Finally, there is variation in the density and size of the punctures on the head and mesosoma, and in the texture of the interspaces. As a result of weaker background sculpture (i.e. interspaces tending to be smooth and shiny), the sheen of the integument is generally stronger in eastern coastal populations, when compared with samples from drier inland localities.

Ward (2001) - Tetraponera punctulata is the most wide-ranging species of Tetraponera in Australia, occurring across much of the continent except the far south and parts of the arid interior. Isolated populations occur in the Flinders Ranges of South Australia and in the MacDonnell Ranges of central Australia. In MHNG there is an old worker from “Geelong, Viktoria” (leg. Davey), but I suspect that this has been mislabeled. There are no contemporary locality records anywhere near the state of Victoria. Outside Australia T. punctulata is known from a number of sites in southern Papua New Guinea.

Ward (2001) - Most localities from which T. punctulata has been recorded are in Eucalyptus woodland or open forest. In the more northern parts of Australia and in savannas near Port Moresby, Papua New Guinea, workers are often seen foraging on the trunks of Eucalyptus trees, and nests occur in dead branches in the canopy of the same trees. Specific nest site records include dead branches of E. alba, E. camaldulensis, E. dichromophloia, E. maculata, and E. papuana. Other habitat records include riparian woodland (Western Australia), monsoon gully forest (Northern Territory), mangrove (Northern Territory, Queensland), rainforest (Queensland, Papua New Guinea), gallery rainforest (Queensland), urban parkland (Queensland, Papua New Guinea), and littoral vegetation (Queensland). Nest site records from these other habitats include dead twigs or branches of Avicennia eucalyptifolia, Calophyllum inophyllum, and Rhizophora sp.
Tetraponera punctulata is able to occupy large dead branches, often composed of rather hard wood, by taking advantage of cavities previously excavated by coleopteran and lepidopteran larvae. I have twice encountered colonies whose galleries extended into live wood and in both instances the workers were tending coccids in the nest. One such nest was in branches of Eucalyptus camaldulensis (47 km S Derby, Western Australia) with scales of the genus Myzolecanium. The second record was from a live, beetle-bored branch of Avicennia eucalyptifolia (Scraggy Point, Hitchinbrook I., Queensland), with scales identified as ?Coccus sp. These observations point to the kind of biology that might characterise transitions from generalist nesting habits to specialised ant-plant inhabitation (Ward 1991).
